Texas Instruments UCC25660 | Demoboard UCC25660EVM-064

Description

The UCC25660EVM-064 assists designers to evaluate the operation and performance of the UCC25660x LLC Resonant controller (16-pin SOIC package with removed pins for high voltage clearance). This evaluation module demonstrates how UCC25660x controls the LLC resonant half bridge DC-DC converter to achieve high efficiency throughout the load and input voltage range

Features
